Abstract of the Disclosure A synthetic fiber substantially comprising: (A) 5-40% by weight of a copolymer consisting of (a) 20-80% by weight of polyvinyl alcohol, and (b) 80-20% by weight of acrylonitrile, and (B) 60-95% by weight of a copolymer consisting of (c) 55-95% by weight of styrene, and (d) 5-45% by weight of acrylonitrile. This fiber is used for producing paper and has a potentially fibrillar texture. When beaten, it forms synthetic pulp having stalk fibrils and micro fibrils extending from the stalk fibrils. High-tenacity synthetic paper can be made because this synthetic pulp is self-adhesive.
